Variations in Salivary Stress Biomarkers and Their Relationship with Anxiety, Self-Efficacy and Sleeping Quality in Emergency Health Care Professionals

Coping and Quality of Life Differences between Emergency and Rehabilitation Healthcare Workers

Audit and Feedback (A&F) is a systematic process involving the collection of data, which are subsequently compared with the established reference standards and then subsequently disseminated to healthcare providers through feedback meetings. This allows continuous improvement to be ensured in the quality of care processes. Often, the parameters taken into account concern only the patient and the treatment processes, neglecting other variables. Quality of life in the workplace and coping skills are determining variables for the clinical performance of all healthcare professionals. For this reason, in this study, these variables were investigated and differences were highlighted in two different role categories and context: cardiovascular emergency and neurological rehabilitation. A psychological screening was carried out by sending the computerized Coping Orientation to Problems Experienced-Nuova Versione Italiana (COPE-NVI) and Professional Quality of Life Scale-5 (ProQoL) questionnaires to all healthcare workers involved. Ninety-five healthcare providers (mean ± SD age: 47 ± 10.4 years; 37.9% male) answered the questionnaire and were assigned into two groups (G1 and G2) based on the ward in which they worked. These were further divided into two subgroups (R1 and R2) based on their role. The obtained results show that avoidance strategies are used more by health professionals working in rehabilitation (G2) wards than in intensive-care units (G1). Moreover, in G1 nurses, physical therapists and speech therapists (R2) obtained higher scores in terms of turning to religion (TR) and compassion satisfaction (CS), while physicians and psychologists (R1) obtained higher scores on the burnout scale (BO). The TR score for R2 was found to be higher, even in G2. The response trend of the two groups in the different departments was analyzed and commented on.

Relationship between Strength and Professional Quality of Life of Nurses Working Hospital Emergency Departments

Optimal quality of professional life can allow coping with stressful situations and avoiding fatigue. This is instrumental in jobs undergoing very demanding situations, such as nurses working in Emergency Departments. In this study, we investigated the relationship between functional and physiological indicators and the quality of professional life in nurses of Emergency Departments of two public hospitals. Fifty-nine professionals participated in the study. Cortisol (an indicator of stress) and post-test lactate (an indicator of fatigue) were analyzed in saliva and in the blood, respectively, at the beginning and at the end of the morning shift. The CVP-35 survey (Spanish version of the QPL-35 questionnaire) was used to assess the quality of professional life. Post-dynamometry circulating lactate levels increased significantly; meanwhile, salivary cortisol decreased in participants at the end of the working shift. Regarding dynamometry, no significant changes were observed. CVP-35/QPL-35 scores did not show significant changes in participants from both hospitals in all dimensions analyzed. In conclusion, nurses participating in the study displayed adaptation to stress accompanied by an acceptable level of professional quality of life. However, certain fatigue appears at the end of the working day. Altogether, results suggest that a better organization must be implemented at work, improving ergonomic, safe, and healthy conditions.

Interest of the BLAST paradigm and salivary markers for the evaluation of sleepiness in drivers

Objectives

Sleepiness is associated with decreased cognitive abilities and remains one of the main causes of fatal road accidents. The tools currently available to assess sleepiness, such as questionnaires, are subject to intra- and inter-individual variability, while multiple sleep latency tests are only feasible in few sleep laboratories. The main objective of this study was to explore new potential markers (neurocognitive, biological) to objectively assess sleepiness in drivers.

Methods

A total of 186 drivers (median age 44 years, range 20-74 years, 73% men, 14% obese) were included during a break at a highway service area, in the morning, while on the road for vacation. Questionnaires on sleepiness and sleep characteristics (habitual and on the night before travel), the Bron-Lyon Attention Stability Test (BLAST), and two salivary samples (α-amylase and oxalate) were collected. Associations between measures of sleepiness [Epworth Sleepiness Scale (ESS), and Stanford Sleepiness Scale (SSS)], sleep characteristics, neurocognitive, and biological markers were tested using regression models adjusted for confounding factors.

Results

The night before travel, 83% of the drivers reduced their sleep time and 30% slept 5 h or less. The higher the number of miles to be traveled, the higher the decrease, and the shorter the sleep time. The night before travel, 18 and 24% of the drivers complained of poor sleep quality and difficulty falling asleep. The sleep characteristics on the night before travel were associated with the habitual sleep characteristics. At the time of the test, 47% of the drivers scored pathologically on the SSS. Poor sleep quality and difficulty falling asleep the night before travel were associated with increased sleepiness as assessed by the SSS and decreased attentional ability as assessed by the BLAST. No association between salivary markers and acute sleepiness was observed.

Conclusions

The sleep characteristics of the night before travel were associated with sleepiness and attentional performance. The SSS and the BLAST could be used by individual drivers in a self-evaluation context. Biological markers showed a high variability and limited association with sleep parameters across subjects, emphasizing the need for within-subject designs to assess their usefulness.

Professional Quality of Life of Healthcare Workers in Hospital Emergency Departments

In previous publications, we have reported that professionals in emergency departments undergo high levels of stress according to the amounts of salivary biomarkers (α-amylase and cortisol). The stress seems to be counteracted by increased levels of dehydroepiandrosterone. This hypothesis is confirmed in the answers to different tests indicating no working stress, no anxiety, optimal self-efficacy, and good sleeping quality. Altogether, these previous results suggest an optimal adaptation of these workers to the demanding situations that occur in emergency departments. To complete this research, we decided to evaluate the quality of life of health professionals working in the emergency departments of two Spanish hospitals. A descriptive cross-sectional study was carried out during the pre-pandemic months of July and August 2019. We determined the professional quality of life through the QPL-35 questionnaire in 97 participants, including nurses (n = 59) and medical doctors (n = 38). Answers to the test indicate that the studied participants working in emergency departments have a good perception of professional quality of life. This is reflected in the three dimensions of the questionnaire: managerial support, workloads, and intrinsic motivation. Based on the results of all answered tests, emergency healthcare staff seem to have adequate professional management, with levels of stress, sleep, and quality of life in line with a controlled lifestyle. Altogether, this would allow a correct adaptation to the demanding situations experienced in emergency departments. The relevance to clinical practice is that the COVID-19 pandemic has disrupted this controlled professional management.
